FAQ
Do Hong Konger nationals pay Thai tax if they stay under 180 days?
No — you are not a Thai tax resident. Only Thai-sourced income (e.g. rental from a Thai condo, salary from a Thai employer) is taxable.
What does BOI Promotion Amendment start at?
From quoted on request + 7% VAT — fixed quote before we start.
How long does it take?
30–60 at BOI once documents are complete.
How does the Thailand-Hong Kong SAR DTT actually reduce my tax?
We obtain the Certificate of Residence from the Revenue Department, then you file it with the Hong Kong SAR tax authority to credit the Thai tax already paid — up to 100% of the overlap.
Can this be done while I'm overseas?
Yes — sign a POA + courier documents via DHL. We file and return the receipts.
